Lightning
The front-panel LIGHTNING button is used for both the Light-
ning display and the Diamond display. For Lightning dis-
play, use the
CONFIG—FORMAT menu (page 3-21) to set the
DISPLAY to LIGHTNING and select the appropriate format for
your system. Push CLEAR MENU to clear the menu readout.
Selecting Lightning mode forces the instrument to A123 in-
put display; it can be changed to B123. Apply component
signals Y, P
B and P R to the rear panel connectors for CH-A1,
A2, and A3 or CH-B1, B2, and B3. Procedures for using the
Lightning display can be found in the Operator’s Checkout
and on page 4-16.
NOTE
A123 (or B123) must be configured as a compo-
nent input. See
CONFIGURE menu, page 3-20.
Diamond
For a Diamond display, push the LIGHTNING button and use
the CONFIG—FORMAT menu to set DISPLAY to DIAMOND.
Apply a component signal to the rear panel connectors for
CH-A1, A2, and A3 or CH-B1, B2, and B3. The Diamond
display evaluates the GBR signal for gamut limit violations
and color errors due to gamma correctors. Signals which are
inside the electronic diamond graticule are within gamut lim-
it. For signals outside the diamond, the graticule is labeled
with G, B, and R to determine the color problem area.
NOTE
A123 (or B123) must be configured as a compo-
nent input. See
CONFIGURE menu, page 3-20.
